Commercial HVAC systems can have major leakage problems, often losing 15% to 20% of conditioned air and sometimes even more. Sealing leaks by conventional methodology (mastic) is problematic because it requires finding each leak and having direct access to all sides of the duct. Also, the aged mastic can crack or dry out over time resulting in increased leakage over time. Aeroseal dramatically reduces leakage in air ducts with a revolutionary technology that allows an atomized sealant to “find” the leaks in the system, and accumulate around the edges of the leaks until they are filled with a flexible, durable seal. Aeroseal typically reduces leakage by 80% to 95% and sometimes even more.
Sealing inaccessible risers with the Aeroseal® process cut leakage by 90% and allowed the project to be completed.
